I actually shot Colt 21AC #5697 at the Buffalo Rock Shooter's Club in the spring of 1974. Put a few 20rd sticks through it. From what I understand, the gun was partially burned and water damaged from the fire. The wood was gone and the metal surfaces rusted. It was subsequently restored by a shop Southwest of Chicago. They also had another Colt Thompson, which I recall being a 21/28 Overstamp.
